I was looking for solar lights I could hang from the drainage gutters on my house. These lights were exactly what I was looking for. They work as advertised but take the negative reviews lightly. For me these lights last from dusk to dawn with no issues. We have had several rain storms since I put them up and they are still working. In order to last all night they will need at least 8 hours of full sun to charge. I think the negative reviews on longevity are because the end-user installed them in a shaded area that does not get sufficient sunlight long enough. These are solar lights and they require full sun to charge the battery efficiently. They will charge in low light but the charge will be minimal and the performance will be poor. The manufacturer recommends charging them for a full 8 hours before using them but they work efficiently right out of the box for me.

These are incredible. I do not work for these guys. No. I bought 5 of these, then later (this shipment) bought 5 more.
This is a great price and let me tell you, that I have 6 of these mounted on the drainage gutter above my front porch and it is very bright.
After several months the solar panel on top will discolor a milky white it does NOT affect their recharge or performance.
I am very impressed.
At first I had put 3 there and it was ok, but not what I wanted, then I placed a 4th and it was pretty good. Then I placed a 5th one and that did it!
5 of these together make a porch light! You may think that is overkill but to me, saving money is not trivial!
Now, I literally just placed a 6th one and will see tonight, but it was already very bright so I expect more.
I also have 3 on the side gutters (above) on the side of the house and 2 right above and beside my side gate leading to the back yard.
In the backyard I have eLEDing Pure Digital Solar Powered Motion Activated LED Security Flood Lights
